51 * Erratum A-004034
53 * Description: During port initialization, the SRIO port performs
58 * the configured port width.
59 * An SRIO port configured as a 4x port may see one of these scenarios:
60 * 1. One or more lanes fails to achieve lane synchronization. Depending
61 * on which lanes fail, this may result in downtraining from 4x to 1x
62 * on lane 0, 4x to 1x on lane R (redundant lane).
64 * all 4 lanes achieve lane synchronization, and downtrain to a 1x.
65 * An SRIO port configured as a 1x port may fail to complete port
66 * initialization (PnESCSR[PU] never deasserts) because of scenario 1.
67 * Impact: SRIO port may downtrain to 1x, or may fail to complete
68 * link initialization. Once a port completes link initialization
